I put just about anything in mine, they have the giant sized ones and their favourite is a big chunk of cheese wedged right in. I also put chicken in, almost anything I have really that they can have. So long as it takes them an age to get out, they are happy.
My female is clever though, she throws it across the floor to try to get bits to fall out. I bought the kong filler once, it was a waste of money for me as they had it within a day.
